Tips On How To Keep A Fish Tank Clean Without Changing Water
1. Use an Aquarium Vacuum
It is highly recommended to buy an aquarium vacuum cleaner.
This is responsible for cleaning the bottom layer of the fish tank without compromising anything else including the water quality.
As you learn how to keep a fish tank clean without changing water, you will need to have this type of cleaning tool in your hand. A lot of debris can begin to collect inside the fish tank due to the gravel or sand coming loose.
This happens over time and you will want to use an aquarium vacuum cleaner to clean it up. If it continues to muddy the water, it will ruin the water quality over time.
You have to do this as soon as you notice the bottom layer loosening.

2. Invest in a Good Fish Tank Filter
You will also want to take the time to invest in a good fish tank filter.
The right filter will go a long way in making sure the debris and/or excesses found in the water are filtered out through the system. This means the water that is inside the fish tank will be as filtered as it needs to be.
This is critical because a lot of health issues stem from the filter not being good enough.
In an enclosed space such as a fish tank, you need to think about these details to the best of your ability.
3. Scoop Out The Debris
As you learn how to keep the fish tank clean without changing water, you will want to also focus on the debris that is present on the surface of the fish tank.
This can be something as simple as leftover fish food that is now decaying inside the water.
You don’t want this to ruin the water quality because over time it will start creating ammonia. You have to get rid of it as soon as possible.
Look to scoop out the debris as soon as you spot it inside the fish tank.

4. Test the pH Level Often
You will need to buy a good pH testing kit for a fish tank.
The reason to have this is to help test the water quality at different times of the month. This will ensure you have a good read on when a water change is mandatory and when it is okay to go for lesser cleaning solutions.
A lot of people keep this type of kit around to have a finger on the pulse of the fish tank. It just allows you to stay in front of problems.
